CW Pileup Hunter - Complete Guide

CW Pileup Hunter trains practical callsign copy skills for real contest and DX pileup conditions.

1. Quick Start

Open CW Pileup Hunter.
Choose Practice or Daily Challenge.
Press Start Session.
Use Play/Replay to hear the callsign, then submit your answer.
If needed, use AGN (limited credits, with server-side penalty).

2. Modes

Practice: adjustable WPM, Farnsworth, duration, and input mode.
Daily Challenge: fixed challenge for all players, global leaderboard.
Ranked Season: fixed 90-second competitive mode with seasonal ladder.

3. Input Styles

Multiple-choice: fastest mobile-friendly mode.
Typed: full callsign copy mode for precision training.

4. Scoring Model

Server calculates points per round from correctness, response speed, difficulty profile (WPM + impairments), and streak multiplier. Wrong answers reduce points and reset streak.

AGN replays are limited per session and add a penalty in scoring, so use them strategically.

5. Audio Conditions

QRN: noise floor
QSB: fading signal depth
QRM: interference layer
Phase-2 True QRM: overlapping interfering callsign sender
Pileup Density: controls overlap and double-send event frequency

Start with lower impairments and gradually increase difficulty as copy accuracy improves.

6. Keyboard Shortcuts

Space replay current callsign
A request AGN (repeat)
1-5 choose answer option in multiple-choice mode
Enter submit in typed mode

7. Training Tips

Lock onto prefix first, then copy the digit block, then suffix.
Avoid instant AGN; commit first pass copy when possible.
Review top confusion pairs in your stats and train those combinations deliberately.
